Choose the closed style economy steel shelving unit that meets your storage needs from the sizes listed below. Starter units have closed side panels on both sides of the unit, an Add On unit simply has one side panel because it generally bolts to the unit next to it, sharing the common side and eliminating the need or cost to double up on the sides.For example, if you have 3 shelving units along a wall you would want to order 1 Starter Unit and 2 Add On Units.
